Snowflake Obsidian and Cream/White Howlite Silver Tone Beaded Necklace

This stunning necklace features a blend of snowflake obsidian and cream / white magnesite or howlite beads with silver tone clasp and bead accents. Magnesite and howlite are very similar in appearance to each other. I could only offer my best guess since I am not a professional gemologist. Pre-owned. Please review photos as they are part of the description including measurements.
